HEULE
What is HEULE?
HEULE is a Swiss tool manufacturer specializing in deburring, chamfering, and finishing holes from both the front and back sides in machining. The company is especially known for solutions that allow drilled holes to be finished with one tool and in one pass, even in hard-to-reach places. HEULE's tools are designed to reduce manual post-processing and improve process repeatability in the metalworking industry.
HEULE’s history from a machining perspective
HEULE was founded in Switzerland in 1961 by Heinrich Heule. The company began with a practical machining problem, where chamfering the inner edges of holes was slow and difficult to automate. Since there were no suitable tools available, they developed their own solution. This laid the foundation for HEULE’s specialization in deburring and chamfering tools suitable for serial production and CNC machining.
Over the decades, HEULE has grown from a contract manufacturer into an international specialist tool maker. The company remains family-owned and is now managed by the third generation, which is reflected in their long-term product development and focused specialization.
HEULE and deburring in machining
Deburring is almost always a necessary step after drilling, milling, or turning. Especially when dealing with intersecting holes, deep drilling, and inner edges, manual finishing can be challenging. HEULE’s tools are designed to remove burrs and create chamfers in a controlled manner, directly in the machine as part of the normal machining process.
From a machinist’s perspective, this means shorter lead times, less manual labor, and more consistent results. Deburring can be done in the same setup without separate work steps, supporting automated and unmanned production.
HEULE tool solutions: COFA, SNAP, BSF, and SOLO
HEULE’s product range is based on several different operating principles. COFA tools are designed for deburring and finishing edges, especially in drilled holes. SNAP tools are used for chamfering and countersinking where a precise and repeatable chamfer angle is required.
BSF tools use cutting fluid pressure and are especially suited for back chamfering and leveling of holes. SOLO solutions, on the other hand, are based on centrifugal force, which activates the blade as the spindle speed increases. The common feature of these solutions is the ability to machine both the front and back edges of a hole in one pass without changing tools.
HEULE as part of modern CNC machining
HEULE’s tools have been developed specifically for CNC machining, where process reliability, automation, and repeatability are essential requirements. The tools are suitable for a wide range of materials and are used in both single-piece and serial production machining.
In machine shops, HEULE is often combined with other cutting tools as part of an integrated process, where drilling, chamfering, and deburring are all done accurately in a single workholding setup. This ensures high-quality results and reduces the risk of dimensional deviation.
Summary
HEULE is a long-established Swiss specialist tool manufacturer whose core expertise lies in deburring and finishing holes in machining. The company's solutions are developed to meet the needs of the metalworking industry, where efficiency, automation, and consistent quality are key. HEULE’s tools make it possible to finish even challenging edges and holes directly in the machine as part of the normal machining process.
